Key Takeaways:
The Financial Stability Board is calling for greater scrutiny of the nearly $2 trillion private credit market, flagging potential risks to the global financial system just as a class-action lawsuit brings those concerns to life.
"This is exactly the kind of shadow risk the FSB is worried about," said Michael Hayes, head of fixed income strategy at Arbor Research. "The private market's opacity allows valuations to drift from reality, and the correction can be sudden and severe when the truth comes out."
Those risks became tangible for investors in FS KKR Capital Corp. (NYSE: FSK), a major business development company. A lawsuit filed in May alleges the firm overstated its portfolio's health, leading to a 6.2% drop in net asset value per share in one quarter and a subsequent dividend cut from $0.70 to $0.48. The company's stock fell 8.20% and 15.24% after two separate disclosures.
The episode highlights what is at stake in the booming private credit market, which has become a critical funding source for companies as banks pull back on lending. The FSB's warning, issued May 6, points to the industry's complex, opaque structures and the potential for stress to spill over into the broader public markets and banking system, signaling a regulatory crackdown may be on the horizon.
The class-action lawsuit, filed on behalf of investors who bought FSK shares between May 2024 and February 2026, claims the company painted a misleadingly positive picture for five straight quarters. Citing SEC filings and press releases, the suit alleges FS KKR emphasized "portfolio stability" and "attractive distributions" while legacy credit issues were supposedly being resolved.
That narrative began to crumble on August 6, 2025. The company reported its net asset value per share had fallen 6.2% to $21.93, the fair value of its investments dropped by $474 million, and non-accruals—loans not generating income—had climbed to 5.3% at amortized cost. Management attributed the issues to problems at four portfolio companies, including Production Resource Group and 48forty.
The second shoe dropped on February 25, 2026. Full-year results showed NAV had declined again to $20.89, with another $406 million drop in fair value. Non-accruals ticked up to 5.5% at amortized cost, prompting the board to slash the quarterly dividend by over 30% to $0.48 per share. The stock closed at $11.29 the following day, a 15.24% decline.
The allegations against FS KKR serve as a case study for the risks outlined by the FSB. The global watchdog's report warns that the rapid growth of private credit, often extended to riskier borrowers, has occurred largely outside the view of prudential regulators. The lack of transparent data makes it difficult to assess the buildup of leverage and credit risk across the system.
The lawsuit claims FS KKR overstated the value of its portfolio and the effectiveness of its restructuring efforts for troubled companies. On the February 2026 earnings call, the company's chief investment officer revealed that the four previously flagged companies only accounted for about half of the losses, with problems emerging in other names like Medallia and Cubic Corp.
For investors and regulators, the case is a stark reminder that fair value marks on illiquid private debt can change rapidly. The FSB's call for better oversight suggests that the era of private credit operating in the shadows may be coming to an end, with potentially significant consequences for the flow of capital to mid-sized and sponsor-backed companies.
